so sad to hear of your loss, it happened to me a the start of this year. took my norfolk terrier to the vet
for what i thought was a routine job... he never came home fcuking cancer. he was only 6.
i had my new beddy who was lost with out him so went and bought a new pup 3 days later.
never can replace your lost ones, chin up mate hope you get a new pup soon.
all the best at this sad time
